| 摘 要： | 对受压翼缘无约束的冷弯薄壁钢梁的屈曲性能进行了有限元分析,将有限元计算结果与不同国家的规范和直接强度法进行了对比分析,验证了有限元程序的有效性,并对现有设计方法进行了修正,修正后的公式可用于受压翼缘无约束的冷弯薄壁型钢的极限承载力的计算。

| Abstract: | The following paper carries out finite element analysis of buckling performance of cool pressing thin-wall steel beam without restriction on compression flange,contrasts and analyzes the finite element calculating results with codes and direct strength methods in different countries,validates the validity of finite element process,and amends the existing design methods,in order to make the mended formula can be used to calculate ultimate bearing capacity of cool pressing thin-wall steel beam without restriction on compression flange. |
